Assuming your data starts in A1 I would put the following in column B:

B1:

=A1

B2:

=B1&","&A2

You can then paste column B2 down the whole column. The last cell in column B should now be a comma separated list of column A.

Can I convert multiple columns to comma-separated lists simultaneously?
Yes, create separate TEXTJOIN formulas for each column in different cells. For automation, use helper columns or write a VBA macro to process multiple columns at once. This is faster for large datasets with many columns.

What's the difference between TEXTJOIN and CONCATENATE?

r/excel on Reddit: Converting multiple columns/rows of text into comma seperated rows of text
June 7, 2023 -

I have an excel that has over 3000+ rows of text in different columns that i need to convert into comma seperated text for csv.

Example:

Column1 | Column2| Column3

Name | surname | phonenumber

Name1 | surname1 | phonenumber1

I need to get all of these converted into the following lines of text:

Name,surname,phonenumber

Name1,surname1,phonenumber1

Bonus points if i can convert them to a text format of:

,"XXX","Name","surname","phonenumber","YYY","ZZZ"

,"XXX","Name1","surname1","phonenumber1","YYY","ZZZ"

The xxx, yyy and zzz being static information that is same for every row.

I can do it row by row with =TEXTJOIN() but i cant add the static information and doing it one row at a time seems tedious.

Help pls :>
